CHURN-ROWER.

SPECIFICATION forming part of Letters Patent No. 437,100, dated September 23, 1890.

Application filed June 3,1890. Serial N0.354,164=. (N0 model.)

To all whom it may concern:

Be it known that I, JOHN S. DICKEY, of Blanket, in the county of Brown and State of Texas, have invented a new and useful Improvementin Churn-Motors, of which the following is a specification.

My invention relates particularly to a vertical single-dasher reciprocating churn, and has forits object to provide a churn-power of the character that shall be simple and durable in construction, one that will give a maximum length of stroke, and one that will always keep the dasher elevated when not in operation.

.With these objects in view my invention consists in the peculiar construction of various parts and their novel combinations, such as shown in the accompanying drawings and hereinafter referred to.

In the drawings forming a part of this specification, Figure 1 is a side view of my improved churn-power. Fig.2 is a rear View. Fig. 3 is a horizontal section on the line 3 3 of Fig. 1; and Figs. 4 and 5 show details of construction, hereinafter referred to.

In constructing my improved churn-power I employ a base or platform B,said base resting on and secured to the sills b and 1), arranged at right angles to each other, the sill I) being adjacent to and parallel with the rear edge of the base, and the sill 1) arranged beneath the longitudinal center of the same. The base B is mortised near its rear edge on each side of the central sill b to receive the tenons of the standard A, and to the rear of the standard A is'arranged a bracing-post A, and resting upon said post and secured to the rear side of the standard is a casting A mortised to receive the gear mechanism, as shown. A metallic brace rod or strap 0 passes over the casting, and is secured at its ends in the opposite ends of the sill b, said brace being adapted to be tightened. when needed to hold the standard more securely to the base. This tightening is accomplished by threading the ends of the bracerods and placing nuts thereon.

The gearing mechanism consists of a driving-gear a, which is mounted on a revolving stud in the casting A and a gear a, mounted on the axle d of the drive-wheel D, said axle d passing through the standard A and casting A the drive-wheel being arranged upon the forward side of said standard. A guideblock E is secured to the upper end of the standard, said block being provided with a circular aperture 6 near its forward edge and an elongated transverse slot 6 near its rear edge. A guide-arm E is secured to the lower end of the standard, said arm being cut away or projected forward to permit the revolution of the drive-wheel D, as shown, the upper end of the arm E being provided with a guidingeye 6 A pitman-rod F is secured at its lower end to the drive-wheel D, its upper end passing through the slot 6, and pivotally connected to said upper end is the upper end of the sliding rod G, said rod passing through the aperture 6 and guiding-eye 6 A horizontal arm H is secured upon the sliding rod G between the block E and guiding-arm E, said horizontal arm H having two Vertical bores h h near the forward and rear ends and the horizontal bores h arranged adjacent to and intersecting a part of the vertical bores. The sliding rod G passes through the rear vertical bore, and the arm H is locked upon said rod by the pin I, said pin passing through the rear horizontal bore and having a cut-out portion adapted to register with and form a part of the vertical bor'e when in a certain position to permitthe passage of the rod, and when given a half turn to bind against the said rod and lock the arm in place. The dasher-shaft K is secured in the forward vertical bore by means of the pin I, which is constructed and operates in precisely the same manner as the rear pin I. 4

L indicates the churn, which may be of any approved pattern, and also the dasher.

The drive-wheel D is weighted at D, a point diametrically opposite the attachment of the pitman; and beneath the block E, encircling the rod G, is a coiled spring G, the said spring being secured at its upper end to the under side of the block E and at its lower end to the adjustable collar g.

The spring G is to aid the operations of the reciprocating mechanism, assisting in lifting the dasher, &c. The weight D is for the purpose of counterbalancing the weight of the pitman, sliding rod, and dasher.

In churns as ordinarily constructed no provision is made for this purpose, and the dasher when not reciprocating invariably rests near the bottom of the churn. Should it be desired to inspect the contents at any time, the mechanism has to be operated sufiiciently to elevate the dasher. By my improved construction the dasher will always rest near the top of the churn when not in motion.

The operation and advantage of my churn are at once apparent to every one skilled in the art to which it relates, and hence a further description is unnecessary.

Having thus described my invention, What I claim as new is In a churn-motor, the combination, with a standard, of an upper guide-block and the lower guide-block, the drive-wheel journaled in the standard, the pitman-rod connected with the drive-wheel and passing through the upper guide-block, the sliding rod passing through the upper and lower guide-blocks, the sliding rod and pitman being connected above the upper guide-block, a horizontal arm located rigidly upon the sliding rod, and the dasher-shaft locked rigidly in .the horizontal arm, a collar secured to the sliding rod between the horizontal arm and upper guideblock, and the spiral spring confined upon the sliding rod between said collar and block, substantially as and for the purpose described.
